Originally the mayor of the town of Trinsic, he joined the Stranger on his quest to become the Avatar in Ultima IV and was a regular companion for the following games. Being quite fond of wine and women, he could usually be found in the Britannian taverns when not traveling with the Avatar. He was knighted between Ultima VI and VII. In Ultima VII Part Two, Sir Dupre sacrificed himself to save the Avatar. He was later resurrected in Ultima IX to help defeat the Avatar's arch enemy, the Guardian.
